Latin īnsectum, from neuter past participle of īnsecāre, to cut up (translation of Greek entomon, segmented, cut up, insect) : in-, in; see in-2 + secāre, to cut; see sek- in Indo-European roots.(American Heritage® Dictionary of the English Language, Fourth Edition)
From Latin insectum ("with a notched or divided body, cut up"), from perfect passive partciple of insecō ("I cut up"), from in- + secō ("I cut"), from the notion that the insect's body is "cut into" three sections. Calque of Ancient Greek ἔντομον ("insect"), from ἔντομος ("cut into pieces"). (Wiktionary)
